It was a pleasure to stay at the Siamese Exclusive Queens! The hotel is amazing, specially the pool at the 33th floor and the cheap rooftop bar/ restaurant at the 28th floor.
It’s 500 baht from the airport with taxi, reachable in 30min. (use the app ‘Grab’), also there is a MRT (metro station) right next to it to drive easy into the city.
If you have troubles to find the hotel in Maps, just write the hotel name ‘Siamese Exclusive Queens’ and you will get the correct address.
If you are still reading the comments, just stop and book it. It was an amazing stay and I will go back to, whenever I’m in Bangkok.
